HEATING AND COOKING RANGE.

Specification forming part of Letters Patent N0. 47,706, dated May 16,1865.

To all whom it may concern:

Be it known that I, EBEN EDWARDS, of Boston, in the county of Suffolkand State of Massachusetts, have invented an Improved Range for CulinaryPurposes and for Heating Air for Warming Apartments; and I do herebydeclare the same to be fully described in the following specificationand represented in the accompanying drawings, of which- Figure 1 is avertical and transverse section of it, the plane of section being at themiddle of the oven and lire-place. Fig. 2 is another such section, theplane of which is through one of the lateral conduits of thesmoke-chamber of the hre-place. Fig. 3 is a longitudinal section of thefire-place. Fig. 4 is a longitudinal section taken through the oven andexhibiting the radiator above and Fig. 5 is a horizontal Fig. 6 is afront elevation.

In the said drawings, A denotes the lireplace or fuel-chamber, which issurmounted by a smoke-chamber, B, which projects horizontally over orbeyond each end 0f the said fire-place in manner as shown invFig. 3, andhas a series of holes, a a a a, arranged in its top plate, such holesbeing for the reception of boilers or vessels to be heated. The replaceis provided with a grate, C, and is situated over an ash-chamber, D.There is a shallow throat, E, leading out of the front and middle of thesmoke-chamber B. vAbove and in rear of the re-place is the oven E, whichis situated within a chamber, F, of larger dimensions, the said chamberextending around the top, bottom, two ends, and rear part of the oven,and so that there may be a free space, G, between it and such "parts,This fluespace communicates with the replace by means of a pipe, H,which leads out 0f the middle of the smoke-chamber, and has at itsentranceinto the space above the oven, a damper, I. A hollow drum orradiator, K, is arranged above and in rear of the oven-iiue chamber, andcommunicates therewith by means of a pipe, L, leading out of the top ofthe hue-space and into the middle of the radiator. Furthermore, fromeach of those parts of the smokechamber which projects beyond thehre-place a conduit or radiating-pipe, M,

is led toward and into the radiator K, the same being as represented inFig. 2, such conduits serving to convey smoke from the chamber into theradiator. Each of these conduits, where it opens into the smoke-chamber,should be provided with a damper, N. An escapeiiue, O, leads out of theback part of the radiator and serves to discharge the smoke therefrom.`

The whole lire-place, ash-chamber, oven, oven-flue, chamber, radiator,and the lateral conduits, as above described, are situated within anairheating space or chamber, P, which should be provided with conduitsfor the ingress and egress of air, to be warmed by contact with theexternal surfaces. of the fire-place, the oven, flue-case, the radiator,and the lateral conduits. The smoke-chamber is also sunk within theair-heating space or chamber, and contributes toward heating the airthereof. The oven opens through the front Wall of the air-heatingchamber, and has doors R R applied to it in the usual manner. There isalso la door, T, to the ash-chamber,

and one, U, to the throat of the smoke-chamber. Furthermore, at one endof this replace two tubes, V W, are led horizon tally to and through theend wall of the air-chamber. One of these tubes is arranged over theother, and both are in a plane passing vertically through the middle ofthe grate. Opposite the said tubes V W there are in the op` posite endof the fire-place bearings .w x for the reception of a journalprojecting from the grate, the other journal' of the grate being madesquare and to rest in a corresponding socket or notch formed in one endof a shaft, X, which is extended through one of the tubes V W. In otherwords, the connection of the grate with the shaft should be such as notonly to enable the former to be readily disconnected from the latter,but to cause the shaft while beingrevolved to revolve or turn the gratemore or less, as circumstances may require in order to discharge coalsor ashes therefrom into the ash-chamber.

While the tubes V W and the bearings x enable the grate to be arrangedat different elevations in order to either increase or diminish thecapacity of the fuel-holding space, the said tubes serve other usefulpurposesthat is to say, while that one of them on which the shaft may beplaced operates to prevent ashes from being discharged from thelire-place into the air-chamber, the other tube will answer as a meansof supplying air to the fuel While in a state of combustion.v

From the above it will be seen that my invention consists, mainly, in apeculiar arrangement of parts whereby air received into a chambersurrounding such parts may be warmed to good advantage before beingdrawn into one or more apartments connected with such air-chamber bymeans of pipes. I do not pretend that either of the parts involved insuch an arrangement is new, and therefore I l'ay no claim to any suchpart. The arrangement is one by which the range, While being capableofperforming ordinary culinary operations of boiling and baking, is ableto heat air to excellent advantage and with much economy.
